We tried to answer this as precisely as possible on “What is Interchange” and What is Interchange-Plus Pricing?” pages on this site. Please refer to those pages for more details. But while you are here, we will try to give a short answer to this question.

The primary reason for not giving you an exact rate is lack of visibility to the credit cards you accept. IMD charges a fee based on the costs incurred that are a result of the cards that you accept. Our margin will be consistent and flat but the costs on which the margins are calculated will keep changing because each credit card has a different rate. And the margins are calculated based on those rates.

Therefore, IMD uses Interchange-Plus pricing model which is the considered the best out there. Your monthly statements will give you clear picture of IMD margins, change in card rates, and change in the fee based on that.
